Bug#680519: please do depend on gdm3 for lxde-desktop
I'm one of the lxde maintainers in debian and we have the consens in the
team that we are recommending gdm3 to be used as the display manager for
lxde systems (which can be seen by e.g. looking at
src:lxde-metapackages, until lxdm is in the archive for wheezy+1).
Hence, please use gdm3 and not xdm in tasksel for lxde-desktop.
